“…In addition to the IPFS, different hybrid storage solutions were proposed, including lightweight data structures and a Delegate Proof-of-Stake consensus mechanism, which restricts the number of validators to improve the scalability of the blockchain [24]. Hybrid on-chain and off-chain data storage solutions were described [23,55], such as DoubleChain [24], as well as smart contract filtering algorithms, such as a Distributed Time-based Consensus algorithm, to reduce on-chain data [24]. Additionally, grouping nodes into clusters in the Blockchain of Things infrastructure was suggested to improve blockchain scalability [24].…”

“…A two-way traceability coding scheme was applied to identify and track grain products across a supply chain [67]. Hybrid on-chain and off-chain storage mechanisms, such as Dou-bleChain [24] were additionally described to preserve data privacy with storing sensitive data off-chain [23,24,55].…”

“…The scalability challenge is a major concern of blockchainbased systems for FSCs, because of growing data [51,58] and transaction speed [13,42]. The ongoing research should include the exploration and adoption of decentralized storage solutions, such as IPFS, BigchainDB, Swarm, IOTA, and Algorand, to store data off-chain [23,55,57]. In addition, to improve the scalability of the blockchain, the solutions involving fewer interaction with the blockchain should be considered, such as the routing protocols and routing algorithms for offline channels [65].…”

The lack of transparency and traceability in food supply chains (FSCs) is raising concerns among consumers and stakeholders about food information credibility, food quality, and safety. Insufficient records, a lack of digitalization and standardization of processes, and information exchange are some of the most critical challenges, which can be tackled with disruptive technologies, such as the Internet of Things (IoT), blockchain, and distributed ledger technologies (DLTs). Studies provide evidence that novel technological and sustainable practices in FSCs are necessary. This paper aims to describe current practical applications of DLTs and IoT in FSCs, investigating the challenges of implementation, and potentials for future research directions, thus contributing to achievement of the United Nations’ Sustainable Development Goals (SDGs). Within a systematic literature review, the content of 69 academic publications was analyzed, describing aspects of implementation and measures to address the challenges of scalability, security, and privacy of DLT, and IoT solutions. The challenges of high costs, standardization, regulation, interoperability, and energy consumption of DLT solutions were also classified as highly relevant, but were not widely addressed in literature. The application of DLTs in FSCs can potentially contribute to 6 strategic SDGs, providing synergies and possibilities for more sustainable, traceable, and transparent FSCs.

“…The decentralised database, checks and controls over each transaction and movement and continuous vigilance of higher and middle authorities will be the potential benefits of the application of blockchain in PDS. Adopting blockchain technology can help create a trusted information exchange facilitating the visibility of supply chain (Singh et al, 2020). This paper proposes a framework for the application of blockchain technology in the PDS in India, which disperses the subsidised grains to the targeted beneficiaries throughout the country.…”

Purpose The purpose of this paper is to propose a conceptual framework for the application of blockchain in the Public Distribution System (PDS) in India to manage the supply of food grains to the targeted beneficiaries. The framework will help prevent diversions and leakages of grains at the warehouse and Fair Price Shop (FPS) level. The paper also identifies the enablers and disablers in the context of the framework. Design/methodology/approach This paper will firstly review the previous literature in PDS and blockchain-enabled agricultural and food supply chains. The study then proposes a framework that could be implemented in the PDS in India using blockchain technology. Findings The proposed framework provides an effective way to combat corruption, exclusion errors of targeted beneficiaries, leakage of PDS food grains and is cost-effective. The identified enablers and disablers give an insight into the application of blockchain in PDS in India. Research limitations/implications The research work may have implications for the Ministry of Food and PDS (Central Government), Food Corporation of India and State Governments to manage the supply of the grains more efficiently and effectively. Originality/value The current study caters to the implementation of blockchain technology starting from the warehouse level to the FPSs and consumers and simultaneously connecting them to concerned authorities to ensure transparency and accountability.
